Intrinsic quality attributes of beef, and especially its tenderness, depend not only on post-mortem factors associated with meat ageing, but also on muscle characteristics of live animals, which themselves depend on genetic, nutritional and rearing factors. Different breeds or different genotypes of the same breed mainly differ by the characteristics of their connective tissue (content and solu...

Meat tenderness is a concern today in the beef cattle industry, and it will become an even greater concern in the future. • Tenderness is a complex issue, and it is difficult to predict tenderness after cooking by examining raw beef or carcass beef. Unfortunately, tenderness must be evaluated at the carcass level to be a useful tool in the industry. • A star-shaped probe was attached to an Inst...

This article aimed at compiling recent studies on the main factors that influence ostrich meat quality and carcass yield. Few articles investigated the effect of subspecies, which generally are not even mentioned. There are important dietary effects, particularly those caused by dietary protein to energy ratio. Rigor mortis follow-up studies showed that there are no losses in meat quality when ...

Phosphates offer a range of possibilities when used in meat and poultry productions. Food grade phosphates are used in meat products for several reasons such as changing and/or stabilizing of pHvalue, increasing water holding capacity in order to lead to higher yields, decreasing losses of weight in cooking, improving texture and sensory properties (tenderness, juiciness, color and flavor), ext...

Importance of Beef Tenderness Beef palatability is affected by many factors and tenderness is cited as one of the most important. Consumers are willing to pay a premium for a guaranteed tender product with the potential to increase the value of the middle meats over $60 per carcass (Miller et al., 2001). Consequently, the meat industry is in a continual search for methods to improve the tendern...

Genetic markers in casein (CSN1S1) and thyroglobulin (TG) genes have previously been associated with fat distribution in cattle. Determining the nature of these genetic associations (additive, recessive, or dominant) has been difficult, because both markers have small minor allele frequencies in most beef cattle populations. This results in few animals homozygous for the minor alleles. selectio...
